I always want my favorite bands to release great music, but I always want it a little harder with Metallica. The problem is...I don't know if they can. The first song of theirs I ever heard was Enter Sandman, and at that time I could only go backwards in their catalog, which IMO is the best they've ever done, and probably ever will. Load and Reload took a long time for me to warm up to, but both have a handful a songs the good...for what they are. St. Anger...ugh...I tried man, but I just can't stand that album. I heard a band on youtube more or less redo the album and it's not too shabby when remove the snare and ass some balls, but still not what I call Metallica. Death Magnetic is a step in the right direction, but for the most part still seems forgettable to me.
I think one of their main problems is their lack of desire. It's hard to hungry when you're sitting in a pizza palace atop meat mountain. Even if they put another mediocre album, it's still gonna sell millions, and they're still gonna play to sold out crowds. So what's the incentive? I would say musical integrity, but that hasn't stopped them before. But with that being said, I'm right there with you...hoping.
